Final answer:
The correct compound that represents ethanoyl chloride is CH3COCl, also known as acetyl chloride, which includes an acyl chloride functional group attached to a methyl group.
Step-by-step explanation:
The process of converting ethoxyethane (also known as diethyl ether) to ethanoyl chloride involves several steps, including the oxidation of ethoxyethane to ethanol, followed by the oxidation of ethanol to ethanoic acid, and finally the conversion of ethanoic acid to ethanoyl chloride. The correct answer to the question of which compound represents ethanoyl chloride is b) CH3COCl. This is because ethanoyl chloride, also known as acetyl chloride, consists of an acyl chloride functional group attached to a methyl group. The molecular structure for ethanoyl chloride is represented by the aforementioned formula. The chemical process to convert ethoxyethane to ethanoyl chloride would typically require strong oxidizing agents and suitable reagents to facilitate the chlorine substitution.
